Marina Carias has undergraduate in Metallurgical Engineering and Master’ degree in Materials Engineering from Federal University of Ouro Preto – School of Mines, Brazil. Currently, she is part of a research group headed by Prof. Dr. Paulo Santos Assis, connected with Iron and steelmaking, Energy and Environment. She has been engaged in both industrial and research activities mainly concerned with the use of alternatives materials during the coking process and for injection into Blast furnace.

Topic: Biogas: Future of Iron and Steel Making

Abstract: Biogas is the gas generated from degradation of organic material, based especially on methane. The methane is one of the Greenhouse Gas and contributes to this effect. To reduce this contribution, appear new ideas on renewable source of energy, and the use of biogas replacing a part of the material injected on blast furnaces in Iron and Steel making Industry is one of them. Brazil has a large herd animal, making it a major agricultural producers, while rich in natural resources, Brazil has an important role in the steel industry, these two activities now represent the largest contributors to greenhouse gases responsible for the greenhouse effect, the purpose of this paper is to show a solution for these two processes, thus mitigating the emission of polluting gases into the atmosphere. In this study, we noted that the use of agricultural wastes for production of biogas and the use of biogas as auxiliary fuel in blast furnaces. The study showed that Brazil has a great potential to transform the steel industry and agriculture, with a very good results on social and environment areas.
